Fast & Furious star Vin Diesel took it a few steps slower on Valentine's Day.

The actor posted to his Facebook page a video of himself singing along to Rihanna's slow jam "Stay," a mysterious video that he dedicated to his "amores." The stoic action star gave a restrained, purring performance, as he stood cloaked in shadows next to a video screen onto which Rihanna's sultry video for the song was projected.
